The bowling app I wanted to exist.

I'm Jacob — a left-handed league bowler in Colorado. Like a lot of bowlers, I spent years chasing consistency without ever really seeing what my body was doing on the approach. Was my tempo too quick tonight? Was I cutting my follow-through short when I got tired in the back half of a series? I could feel that something was off. I just couldn't measure it.

Every bowling app I tried had the same blind spot: they made me tap my score in after every single frame. That's backwards. The whole promise of an Apple Watch is that it's already on my wrist, already full of motion sensors, already watching every move I make. It should know I just threw a strike before I do.

So I built LaneCaddie. It reads your release straight from the Watch — detecting every shot the moment you let go and capturing the motion behind it: tempo, posting, follow-through, with more on the way. You still tap what fell after each ball, and the Watch keeps your score. No phone on the lane, no guessing why one game felt better than the last.

I built it lefty-first because lefties are an afterthought in almost every bowling product — and because I am one. It works exactly the same for righties. And it's free to start, because the best way to find out whether motion data helps your game is to try it, not to clear a paywall.

What's next

LaneCaddie ships in phases. Automatic shot detection and motion metrics are the foundation. Later in 2026 comes Camera analytics — point your phone down the lane to measure ball speed, entry angle, and breakpoint, and let it fill in your pin count automatically (the first time scoring goes fully hands-free). It's the kind of data that used to live only in $25,000 lane-side rigs. See where we're headed, and follow along for the build.
